When I wrote that part of the spec, it was long before these sorts of
optimizations appeared, and it never occurred to me that they would be.
Does the dmd backend do any such optimisations? I assume not.
No, it doesn't, and I don't intend to add them. I believe they cause more
trouble than they're worth. That applies to some other optimizations I've also
refused to implement, because while legal, they mess up code that most users
believe is correct.
